4 Thank you for your purchase of this Elcometer 6014 Shade and Opacity Meter. Welcome to Elcometer. Elcometer are world leaders in the design, manufacture and supply of inspection equipmt for coatings and concrete. Our products cover all aspects of coating inspection, from developmt through application to post application inspection. Your Elcometer 6014 Shade and Opacity Meter is a world beating product. With the purchase of this product you now have access to the worldwide service and support network of Elcometer. For more information visit our website at 1 ABOUT YOUR GAUGE The Elcometer 6014 Shade and Opacity Meter can be used to assess either the shade of a surface (a simple indication of colour based on lightness/darkness) or calculate the opacity of a coating, plastic film or paper sample. Measuring using 45 /0 geometry, your Elcometer 6014 Shade and Opacity Meter excludes the surface specular reflectance (gloss) compont and looks only at the colour or shade. SHADE MODE: The measured value can be used to grade surfaces from black (0% reflectance) to brilliant white (100% reflectance). Coloured surfaces can also be measured; the value will indicate the luminous intsity of the colour (lightness/darkness). OPACITY MODE: The sample must be drawn down on or measured over a substrate with black and white portions. The instrumt uses these measuremts to automatically calculate the hiding power or opacity of the sample; 0% (transpart) to 100% (totally opaque). The gauge can perform statistical analysis of readings stored in internal memory. 2

5 R The Elcometer 6014 contains a light source, a light detector and a system of lses. A converging beam of light illuminates the specim at a set angle of incidce. The light detector is set at the same angle of incidce and measures a small aperture area of light reflected from the specim. Shade and opacity readings are calculated by the gauge and displayed as a perctage. The gauge is calibrated using certified calibration tiles (one black, one white). The Elcometer 6014 is supported by Novo-Soft software. A data cable connects the gauge to a PC via a USB port. 1.1 GAUGE FEATURES Shade mode: assess the shade of any flat surface from black (0% reflectance) to brilliant white (100% reflectance). Opacity mode: calculates the opacity (hiding power) of any sample measured over a black and white substrate or test plate. 0.1% resolution Move-and-read feature for checking large surfaces quickly Statistical analysis gives an instant indication of batch quality Download, analyse and store readings in Novo-Soft Calibrate to any gloss standard Automatic or manual calibration Automatic standard check during calibration Extded-life light source; over 10 years under normal operating conditions 6014 Shade & Opacity Meter 3

MEAN 89.2 CV 0.12 SD To return to measuremt mode after viewing statistics, press the SCROLL/DOWN key once. In Shade mode, the statistics are calculated for all reflectance measuremts stored in the memory. In Opacity mode, the statistics are calculated for all batched opacity values, therefore no statistics will be se until the opacity has be calculated for at least one set of readings (see Taking a reading - Opacity on page 10). c. An explanation of the statistical analysis is giv in Statistics terminology on page

16 7 CALIBRATION 7.1 CERTIFIED CALIBRATION TILE Before taking readings it is necessary to adjust the calibration of the gauge using the certified calibration tiles. The calibration tiles are supplied certified in a clean and defect-free condition. A visual inspection for smears or damage is recommded before each subsequt calibration as dirty or defective tiles may lead to inaccurate measuremts. If necessary the tiles can be cleaned using warm soapy water and dried with a soft lintfree cloth. The calibration tiles are mounted in matt foam in a protective case. The tiles are certified with traceability to the BAM standards. Black (zero) calibration tile White calibration tile 14

17 7.2 CALIBRATION MODE - AUTOMATIC / MANUAL The Elcometer 6014 has two calibration adjustmt modes; Automatic and Manual. Automatic calibration (default mode, set at factory) - sets the gauge to the value of the calibration tile pre-programmed in the memory of the unit. Manual calibration - allows the reading value displayed on the scre to be adjusted up or down to the value giv on the calibration tile label. To switch betwe the two calibration modes, connect the gauge to a PC, run Novo-Soft software and choose the appropriate setting in >Setup>Software preferces (see Changing settings using Novo- Soft on page 29). 7.3 CALIBRATING IN AUTOMATIC MODE The automatic calibration procedure is as follows: 1.

33 12 MAINTENANCE The Elcometer 6014 Shade and Opacity Meter is designed to give many years reliable service under normal operating and storage conditions. Regular calibration checks over the life of the gauge and the certified Last Certified: calibration tile are a requiremt of quality managemt procedures, e.g. ISO 9000, and other similar standards. Wh the gauge is switched on 17/10/2007 the date of last certification is displayed on the scre. For checks and certification contact your local Elcometer supplier. The gauge does not contain any user-serviceable componts. In the unlikely evt of a fault, the Elcometer 6014 should be returned to your local Elcometer supplier or directly to Elcometer. The warranty will be invalidated if the instrumt has be oped. Contact details can be found on the outside cover of these instructions, or on the Elcometer website, MAINTAINING YOUR CALIBRATION TILES The tiles should be checked on a regular basis to sure that they are clean and in good condition. If necessary a tile may be wiped with a cloth moisted with warm soapy water and dried with a lint-free cloth. Marks on the surface of the white tile should be removed by scraping carefully the surface of the tile using a scalpel. For accurate calibration, a flat surface must be maintained. If the tile is damaged with deep scratches, a replacemt tile must be purchased. It is important that a calibration tile has an up-to-date certificate and the normal rewal period is 12 months. However, it should be noted that if successive calibration certificates give the same value for the tile, extsion of the rewal period to 24 months is permitted. 31

34 12.2 MAINTAINING YOUR GAUGE Before use, check that the metal base of your gauge is clean and free of any damage. The optical cavities and lses must also be free of dust or any other contamination. Wh the battery voltage falls below the required level to operate the gauge, the display will briefly show a warning message, see below, and th switch itself off. Fit new batteries. 13 STATISTICS TERMINOLOGY For this purpose the individual readings are defined as values x 1, x 2, --- x n and x i is any reading in the data set. Statistical sample population, n: The currt number of stored readings (STORE), on which the statistical calculations are based. Maximum (MAX): The highest reading in the data set. Minimum (MIN): The lowest reading in the data set. Mean (MEAN): The average value for the data set. The sum of all the individual readings divided by the total number of readings. Standard Deviation (SD): Square root of the sum of squared deviations from the mean. Coefficit of variation (CV): Standard deviation divided by the mean; a measure of the data scatter that can be compared for differt mean values. 32
